"They slithered and twittered and jangled, for they were not men. There was only one man - Jarcal - and he was the last of his kind. 

The advancing vacuum of the voids had sucked Jarcal's worlds into nothingness. But the aliens around him denied its existence; they gibbered inanely when questioned. And then, when Jarcal was discovered to be possessed, they most happily cast him out. 

But if Jarcal was possessed, he was also chosen. For the red dancing slippers of the gods led him through a mission to Armageddon...."
